About Fuel Calculator
A tool for calculating fuel efficiency from distance and fuel, or fuel cost from efficiency and distance. Also supports EV electricity cost calculations.
Compare annual costs by car type to estimate maintenance expenses.
📖How to Use
- 1Enter the distance traveled and fuel volume added
- 2Set the fuel price to also calculate cost per kilometer
- 3Track multiple fill-ups to monitor fuel efficiency over time
💡Tips & Knowledge
- •Fuel efficiency (km/L) = distance ÷ fuel volume. The full-tank method is the most accurate
- •Maintaining proper tire pressure alone can improve fuel economy by 1–3%
- •Air conditioning reduces fuel efficiency by about 10–15%. Use natural ventilation when weather permits
